"We took the i3 design of Josef Prusa. Our i3 Berlin has further improved the ease of assembly. We made the looks more consistent and clean. We also added some extra functionality like easy folding mechanism, display and electronics casing. What you cannot see from the pictures is the effort we put in debugging the mechanical parts. We have tested the parts over and over again, so we are really sure that everything fits seamlessly.

"Like every printer, this model has some disadvantages that you should keep in mind while using it. The Y unit is sensitive for torque, causing non-parallel motion of the bed. Additionally there´s the 2 Z-motors. If one of the motors jams, then the x-bridge is out of calibration. Regular checks on these issues will ensure happy printing."

The design is published under a Free License on github. If you buy all the parts specified in the BOM you’ll end up spending approximately €750.-.
